# realtime-sync
|
|
|
|
realtime synchronisation daemon for OpenOS
|
|
|
|
realtime-sync uses the Date: header in HTTP responses, using the Internet card, to ascertain the current real time in UTC, and updates the realtime library with this information.
|
|
|
|
## Usage
|
|
|
|
realtime-sync is implemented as an rc service, and as such, to start it one can use the usual rc commands:
|
|
|
|
rc realtime-sync start
|
|
rc realtime-sync stop
|
|
rc realtime-sync enable
|
|
rc realtime-sync disable
|
|
|
|
Additionally, realtime-sync includes
|
|
|
|
rc realtime-sync sync
|
|
|
|
to force a re-synchronisation.
|
|
|
|
## Configuration
|
|
|
|
realtime-sync includes a configuration file at */etc/realtime-sync.cfg*; as a Lua table. It contains the following fields:
|
|
|
|
- **url**: The URL to request to get the time. Pick one that returns UTC dates in the headers, or leave the default.
|
|
- **offset**: The timezone offset, in hours. For example, for AEDT, use 11.
|
|
- **frequency**: The time between automatic time synchronisations.
